shown, have the vehicle inspected at your Toyota dealer.
■ If “Traction Battery Needs to be Protected Refrain From the Use of
Position” is shown
This message may be displayed when the shift position is in N.
As the hybrid battery (traction battery) can not be charged when the shift
position is in N, shift the shift position to P when the vehicle is stopped.
■ If “Traction Battery Needs to be Protected Shift into to Resta rt” is
shown
This message is displayed when the hybrid battery (traction battery) charge
has become extremely low because the vehicle has been left with the N shift
position selected for a certain amount of time.
When operating the vehicle, shift to P and restart the hybrid s ystem.

To inject the sealant and inflate
the tire, turn the compressor
switch on.
Inflate the tire until the specified air pressure is reached.The sealant will be injected
and the pressure will spike to
between 44 psi (300 kPa,
3.0 kgf/cm
2 or bar) and
58 psi (400 kPa, 4.0 kgf/cm2
or bar), then gradually
decrease.
The air pressure gauge will
display the actual tire infla-
tion pressure about 1 to 5
minutes after the switch is
turned on.
• Turn the compressor switch off and then check the tire
inflation pressure. Being
careful not to over inflate,
check and repeat the inflation
procedure until the specified
tire inflation pressure is
reached.
• The tire can be inflated for about 5 to 20 minutes (depending on
the outside temperature). If the t ire inflation pressure is still lower
than the specified point after inflation for 25 minutes, the tire is
too damaged to be repaired. Turn the compressor switch off and
contact your Toyota dealer.
• If the tire inflation pressure exceeds the specified air press ure, let
out some air to adjust the tire inflation pressure. ( P. 691, 725)

Water can be used in an emer-
gency if coolant is unavailable.
Start the hybrid system and turn the air conditioning system on to
check that the radiator cooling fans operate and to check for
coolant leaks from t he radiator or hoses.
The fans operate when the temperature setting is adjusted to “LO” and
